Can i add payroll for previous period

Hi reme_81,

It's great that you're looking to get a more extensive history of your payroll into QuickBooks Online. Tax tables are automatically optimized for the current year, so you can rest assured calculations will be accurate as long as your year-to-date info is entered correctly. To ensure maximum consistency across your books, it's not recommended to record payroll for a previous calendar year. I'll be happy to assist you with alternative options to get this information entered.

The best way to get prior year payroll information into QuickBooks Online is using journal entries. This lets you have full, detailed breakdowns of your payroll liabilities and expenses, without affecting your payroll subscription. You can even copy your first journal entry to make subsequent ones easier. Here's a great article to get you started: Record payroll transactions manually
